摘要
A polycrystalline diamond compact (PDC) cutting element includes a substrate and a polycrystalline diamond compact. The substrate comprises a ceramic-metal composite material including hard ceramic particles in a metal matrix. The polycrystalline diamond compact includes interbonded diamond particles. Interstitial material disposed within interstitial spaces between the interbonded diamond particles comprises aluminum and at least one element of the ceramic-metal composite material of the substrate. A method of manufacturing such a PDC cutting element includes forming a mixture including diamond particles and particles of aluminum, and subjecting the mixture and a substrate to a high pressure, high temperature (HPHT) sintering process.
